Well like just about any other caliber with the .270 thee is plenty of info to go around. I have been loading for and hunting with ours since around '84, and in that time have run the full gamut of bullets and weights for it within reason of price and application to hunting. I've gone as light as 110gr and as heavy as 160 and find that the 130 thru 150 have all three is needed for just about anything walking the lower 48, least anywhere I will be hunting.
In the years I have played with it the powder range from around 4064 to 4831 and slower have been the norm. I have tried them and most in between. The bad or good depending on how you see it is that ours seems to be inherently oblivious to the fact that it should be selective in what it shoots. So it happily digests just about anything I run through it with it's usual 1" or less groups at 100yds. Granted there are differences that seating depth plays a role with but overall, pick a powder, bullet, and shove them in some cases, work up to the velocity you want and then just fiddle with the seating depth till your happy.
The one thing I found that most .270 post I have read through don't mention is using a bit faster powder. When my mom was still in her mid 60's and was still hunting I loaded her up some 130gr Ballistic Tips over a charge of IMR-3031. She needed something with only a little recoil and being this rifle only weighed around 8# at most it had more pop than she wanted. Since then that particular load has taken over a dozen nice deer, countless hogs, and plenty of other critters along the way. It groups consistently around 3/4" at 100yds for as long as you want to shoot it through the same hole. The oldest grandson used it on a nice 250# feral boar at just over 250yds one morning and I told him to put it in his ear, which he did just that. The thing is this load is just barely breaking 2800fps at the muzzle and as most know the BT is a fast expanding bullet which in this case it doesn't explode but is rather tame by comparrison to most other loads. It just does what you want and nothing more even on close shots ranging down to around 20yds.
I have also loaded and shot a ton of the older Hornady 150gr RN as well as some older Speer 150gr RN which I loaded over around 50rgs of IMR-4350. These are not rolling out with the hyper velocity loads either but man do they get the job done. I also have used this same load with some Nosler 150gr Solid Base bullets which unfortunately they dropped from their line, with great success. I mention it since it has shot so well with ours you might give it a try with yours.
Truth be told there really aren't any bad bullets out there, as was mentioned above. The trick is to pick your shot, and put it where you get the least amount of waste, or trimming. For our family, we only take broadside or very slightly quartering shots. We don't like gut soup and having to wash tainted meat off. We also try our best to avoid a point on shot to the shoulder which usually results in some goodly amount of bloodshot meat. It's just something I was brought up doing and have found it is a whole lot nicer to NOT have to deal with those than to. If I am to make a frontal shot it will be high so as not to hit the main paunch area but to hit right between the shoulders and spine or right through the base of the neck shoulder junction. I have never had one not drop at this shot and if the bullet passes completely through it usually goes above most everything inside and exits high on a ham at which point it usually does minimal damage. Not saying this is every case with every bullet just my experiences.
I saw this posted and it struck me as odd,
(Notable exception: Winchester Power Points. They're completely unpredictable and shouldn't be used on paper, let alone an animal.)
My close friend recently purchased a nice lod Remington in .270. He has had minimal time to play with handloads so he picked up several boxes of factory to get it ready for hunting season.
One of the ones he DID try was the Winchester standard loads using the 130gr Power Point. Out of the Hodgdon, Federal, and Remington ammo he tried these consistently shot the best groups and had the best overall SD and velocity over his chronograph. So far those bullets have been three bang flops with about as normal performance as you could want form a standard cup and core bullet. Nice caliber size entrance, lungs and heart both destroyed, and a 3/4" or so exit hole. Shots have been from about 40yds to out just over 150 and the MV from his rifle has been consistent at just over 3100fps.
There again, he is a lot like me, and don't put a shot on the heaviest area of the shoulder, but slips it through the ribs just behind the front leg. He is a VERY picky fellow and would rather not shoot if he can't get the shot he wants.
My oldest grandson is also using these out of his Sako Forrester in a 100gr version .243 with good results as well. So far two bangs and two deer in the freezer.
So I don't know, things could be said, cases can be made about anything or everything. Best thing I can advise is to keep trying stuff till you find what shoots the best, stock up on those cause they might quit making them, and continue on through life having faith in what your using.
